Title: Method and device for determining fundamental quantities of the flux vector of a rotary field machine
Inventor: RENG LEONHARD DIPL ING
IPC: H02P21/14
Filed: 1983-05-27
Abstract: For the field-oriented operation of a rotary field machine, the direction (angle  phi ,u) of the electric flux ( psi ) is determined by an electrical computing model. For this purpose, a "voltage model" (11', 12) forms the induced EMF from voltages and currents, the integral of which is picked up as flux vector ( psi ,u). At low operating frequencies, this flux determination is too inaccurate. For this reason, a model flux vector  psi ,i is determined from stator current and rotor position  lambda in a "current model" (7) and the input vector of the integration is corrected by means of a correction vector determined by the output signals of two controllers. According to the invention, one controller is supplied with the difference of the two flux amounts and the other controller is supplied with the angular difference between the two directions of the flux vectors psi ,i and  psi ,u. <IMAGE>

Title: Device for varying phase and/or polarisation of the light wave running in an optical waveguide, and method for producing such a device
Inventor: MOHR FRIEDEMANN DIPL ING
IPC: G02F1/01
Filed: 1983-10-20
Abstract: The device consists of a body (2) made from ceramic, piezoelectric material, such as lead zirconate titanate, for example, which is polarised and carries electrodes (3, 4) on the outer surfaces. An optical waveguide (1) is fastened in a capillary duct of the body (2) by means of a rigid bonding agent (5). The direction of polarisation can extend parallel to the axis of the optical waveguide (1) or perpendicularly thereto. The capillary duct can be produced in a simple way by embedding a glass fibre in the starting oxide mixture for the body made from piezoelectric ceramic material. During firing of the body, the glass diffuses into the interior of the body, the capillaries being produced. The device according to the invention is applied, furthermore, in devices in which the phase and/or polarisation of a light wave running through an optical waveguide is to be influenced. <IMAGE>

Patent DE-3401825-A1 (DE)
Title: Aerodynamic cable winch
Inventor: KNOTT FRANZ JOSEF
IPC: B64D17/78
Filed: 1984-01-20
Abstract: The device uses the drag of an opened parachute as a dynamic hook which requires a cable winch, operated by motor or muscle power, in order to produce lifting, accelerating, or braking forces in the air. This is achieved in that the cable winch winds up a cable more or less quickly, which cable is attached to the parachute and is of suitable length. This thus allows lifting (rescuing) and transportation of people, heavy and cumbersome loads, a soft landing for parachute jumpers and ejected loads, braking and emergency landing of aircraft and muscle-powered flight with vertical takeoff. The forces can, of course, act only briefly on the cable winch, for which reason a "static hook" is required for producing permanent lift, as well as two parachutes, winches and cables, by which hook the parachutes are alternately wound back. The static hook is formed by a balloon, helicopter, etc. The effectiveness of the amount of power required for the lift force of this system which can be achieved stems from the fact that, using this cable winch, muscle power is sufficient to lift people and equipment off the ground, in accordance with the aerodynamic laws.

Patent DE-3420729-A1 (DE)
Title: Prefabricated reinforced concrete slabs serving simultaneously as floors and heating surfaces for buildings
Inventor: SCHEU WALTER DIPL ING
IPC: E04B9/00
Filed: 1984-06-04
Abstract: The invention relates to prefabricated reinforced concrete slabs having concrete-encased heating elements serving simultaneously as floors and as heating surfaces for ceilings or floors for buildings. The surfaces are smoothed in the factory in such a way that the installed slabs can be bonded to the finished floor (PVC, carpet or the like) without an additional topping finish. The heating elements can be the known mats from floor-warming cables, or plastic or metal piping carrying hot water. The hot water is heated up by means of oil or gas boilers, a heat pump or particularly cost-effective electric flow-type calorifiers. The size of the heating surfaces of floors favours a low-temperature heating operation, which saves energy and is also best suited to the use of heat pumps. The storage mass of the reinforced concrete covering slabs permits operation with storage heat and in the case of a heat pump plant renders the buffer store superfluous, and in the case of the use of a flow-type calorifier as heat generating apparatus, the expensive solid or water store otherwise required for an electric storage heating system. Control is performed using the known electric storage heating system charging controllers. Erection is rendered simpler, quicker and less expensive by the slabs according to the invention.

Title: Process for making doped SiO2 layers fuse in fabricating integrated MOS semiconductor circuits
Inventor: PAWLIK DIETER DIPL ING
IPC: H01L21/316
Filed: 1984-07-11
Abstract: In order to level out topographic unevennesses prior to metallisation, the doped SiO2 (4) applied as an insulating interlayer to the substrate (3) provided with polysilicon structures (1) is made to fuse in a gas atmosphere which consists of oxygen and/or nitrogen and has a humidity of between 10 and 30 % by volume of water, at a temperature of less than 1000 DEG C. Owing to the low humidity, the surface oxidation of the substrate (3) is reduced; the fusing ratio is optimal and as good as in the known processes. The process is used in the fabrication of integrated MOS semiconductor circuits by VLSI techniques. <IMAGE>

Title: Installation for double use of water
Inventor: RIECK ADALBERT DR
IPC: E03B1/04
Filed: 1984-07-24
Abstract: The "installation for double use of water" saves water in the home by collecting feed water already used from handbasins, shower and bath, purifying it and then using it for toilet flushing. The installation for this purpose is essentially composed of a collector having a self-cleaning filter unit, an electric pump having specific control means and a pressure water tank. The water already used, on its path into the collector, has contact with disinfectant and lime. The latter causes the soapy suspended particles to flocculate out, which, together with the remaining sediments, collect upstream of a wash-out valve at the bottom of the collector. Floating waste materials are transported with excess water through an overflow pipe into the drains. The filter unit has the effect that water sucked through it passes in an optically pure state via the pressure water tank to the toilet flushing. In a development of the installation, a heat exchanger can bebuilt into the collector in order to reduce the cost of hot water preparation. Furthermore, rainwater can also be fed to toilet flushing or purified in an additional collector and used for other purposes.

Title: Device for point-to-point train control
Inventor: NEUHAUS ALBERT DIPL ING
IPC: B61L1/18
Filed: 1984-09-27
Abstract: In order to synchronise the vehicle-side travel measuring devices of a rail vehicle when the boundaries between tracks sections are passed through, there is provision to transmit a so-called change-over identification (USK) to the vehicle when the respective new track section (GI) becomes occupied. This change-over identification remains present until it can be assumed that it has been detected by the vehicle. After this period has elapsed, the track-mounted device (SG) causes the data telegrams (TG) intended for the vehicle to be output. The synchronisation of the vehicle-side travel measuring devices, which is brought about via the change-over identification (USK), is much more accurate than the synchronisation usually brought about by telegram evaluation because the time margin for reception is very much shorter than in telegram transmission. <IMAGE>
